(McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)1,4-alpha-Glucan Branching Enzyme: In glycogen or amylopectin synthesis, the enzyme that catalyzes the transfer of a segment of a 1,4-alpha-glucan chain to a primary hydroxy group in a similar glucan chain. EC 2.4.1.18.Starch: Any of a group of polysaccharides of the general formula (C6-H10-O5)n, composed of a long-chain polymer of glucose in the form of amylose and amylopectin. It is the chief storage form of energy reserve (carbohydrates) in plants.Isoamylase: An enzyme that hydrolyzes 1,6-alpha-glucosidic branch linkages in glycogen, amylopectin, and their beta-limit dextrins. It is distinguished from pullulanase (EC 3.2.1.41) by its inability to attack pullulan and by the feeble action of alpha-limit dextrins. It is distinguished from amylopectin 6-glucanohydrolase (EC 3.2.1.69) by its action on glycogen. With EC 3.2.1.69, it produces the activity called "debranching enzyme".

An enzyme system having both 4-alpha-glucanotransferase (EC 2.4.1.25) and amylo-1,6-glucosidase (EC 3.2.1.33) activities. As a transferase it transfers a segment of a 1,4-alpha-D-glucan to a new 4-position in an acceptor, which may be glucose or another 1,4-alpha-D-glucan. As a glucosidase it catalyzes the endohydrolysis of 1,6-alpha-D-glucoside linkages at points of branching in chains of 1,4-linked alpha-D-glucose residues. Amylo-1,6-glucosidase activity is deficient in glycogen storage disease type III.Phosphotransferases (Paired Acceptors): A group of enzymes that transfers two phosphate groups from a donor such as ATP to two different acceptors.

It is produced by a parallel process of fertilization in which a second male gamete from the pollen grain fuses with two female nuclei within the embryo sac. The endosperm varies in ploidy and contains reserves of starch, oils, and proteins, making it an important source of human nutrition.Starch Phosphorylase: An enzyme of the PHOSPHORYLASES family that catalyzes the degradation of starch, a mixture of unbranched AMYLOSE and branched AMYLOPECTIN compounds. This phosphorylase from plants is the counterpart of GLYCOGEN PHOSPHORYLASE in animals that catalyzes the reaction of inorganic phosphate on the terminal alpha-1,4-glycosidic bond at the non-reducing end of glucans resulting in the release of glucose-1-phosphate.Solanum tuberosum: A plant species of the genus SOLANUM, family SOLANACEAE. The starchy roots are used as food. SOLANINE is found in green parts.Zea mays: A plant species of the family POACEAE. It is a tall grass grown for its EDIBLE GRAIN, corn, used as food and animal FODDER.Glycogen Storage Disease Type IV: An autosomal recessive metabolic disorder due to a deficiency in expression of glycogen branching enzyme 1 (alpha-1,4-glucan-6-alpha-glucosyltransferase), resulting in an accumulation of abnormal GLYCOGEN with long outer branches. Clinical features are MUSCLE HYPOTONIA and CIRRHOSIS. Death from liver disease usually occurs before age 2.Bacteroidaceae: A family of gram-negative bacteria found primarily in the intestinal tracts and mucous membranes of warm-blooded animals.

However, casein-based film showed a lower water-vapor transmission rate, water gain at different relative humidity conditions, ...
  • Starch is made of about 70% amylopectin by weight, though it varies depending on the source (higher in medium-grain rice to 100% in glutinous rice, waxy potato starch, and waxy corn, and lower in long-grain rice, amylomaize, and russet potatoes, for example). (wikipedia.org)
  • Potato starch is the most powerful of the common thickeners, and resists solidifying as the sauce cools because it is high in amylopectin. (ehow.co.uk)
  • 20 g of potato starch was mixed with approximately 50 ml cold water. (ukessays.com)
  • There are about ten species of economic significance as food and the most important food species are white yam (D. rotundata), yellow yam (D. cayenensis), Chinese yam (D. esculenta) , water yam (D. alata), aerial potato yam (D. bulbifera), cush-cush yam (D. trifida), bitter yam (D. dumetorum) and cinnamon yam (D. opposita) . (thefreelibrary.com)
  • Starch is a good storage material because it is insoluble and so can be accumulated without increasing the water potential of the potato cells. (markedbyteachers.com)
  • This is important in cooking since some candy recipes require creating a saturated solution-where the sugar in water is heated at a high temperature but not to the point where it decomposes, causing the subsequent evaporation of water from the solution. (cosmeticsandtoiletries.com)
  • A "super" saturated solution can be created as water is evaporated, as long as the decomposition temperature of the sugar is not exceeded, since this could alter the scent, taste and/or color of the sugar. (cosmeticsandtoiletries.com)
  • The swollen starch-latex compositions can be prepared in a batch or jet cooker, or by mixing with hot water under controlled conditions (i.e., temperature, pH, mixing, mixing time) in order to make the starch granules swell sufficiently to improve their properties as a filler additive but avoiding excess swelling leading to their rupture. (google.com)
  • Depending on the mash pH, water ratio and temperature, the time required to complete the mash can vary from under 30 minutes to over 90. (howtobrew.com)
  • A compromise of all factors yields the standard mash conditions for most homebrewers: a mash ratio of about 1.5 quarts of water per pound grain, pH of 5.3, temperature of 150-155°F and a time of about one hour. (howtobrew.com)
  • The diced yam tubers were parboiled at temperature of 70[degrees]C and left for 12 hours in the cooking water. (thefreelibrary.com)
  • The modification of starch changes its physicochemical properties i.e. pasting profile, gelatinisation temperature and solubility in water, however these changes do not correlate with digestibility. (media.pl)
  • In addition, the starch digestion in the joshinko particles appeared to be suppressed if the amylose/fatty acid complexes and amylose/flavonoid and amylopectin/flavonoid complexes, which are poor substrates of α-amylase, surrounded the particles. (mdpi.com)
  • The main reason for this long-term durability is the addition of sticky rice water to the standard mortar ingredients (lime and sand) following traditional recipes. (springer.com)
  • The method is characterized in that the agent to be encased is mixed with the encapsulating material under conditions of rigorous and intimate mechanical working with applied high shearing stress but without phase-separating mechanical compression and compaction forces and in the presence of a limited quantity of water and sufficient heat to ensure the formation of a viscous, semi-solid, homogeneous paste constituting a mobile mass or plastic melt. (google.es)
  • If amylopectin is low and amylose high , as in long grain rice (found in grocery stores and super markets), each cooked rice grain is dry and fluffy and remains separate. (whatscookingamerica.net)
  • Starch is a repeating glucose polymer , containing straight amylose chains resistant to water, and high-molecular-weight, branched amylopectin chains. (thefreedictionary.com)
  • 2 quarts of water per pound of grain dilutes the relative concentration of the enzymes, slowing the conversion, but ultimately leads to a more fermentable mash because the enzymes are not inhibited by a high concentration of sugars. (howtobrew.com)
  • Most cereals, especially rice have a high amylopectin content and are therefore easily digested without much gas production. (thenakedscientists.com)
  • Why is it important that water has a high SHC? (brainscape.com)
  • The novel platinum compound has a dimer of glycine as a ligand and one or two carboxyl groups thereof are converted into the ester or salt form to increase the solubility to water and to reduce the side-effect. (patentgenius.com)
  • If amylopectin is predominant , as it is in short and medium grain rice (usually found in Asian stores), the grains have a greater tendency to cling together and make rice sticky when cooked. (whatscookingamerica.net)
  • Humans and other animals that eat plant foods also use amylase, an enzyme that assists in breaking down amylopectin. (wikipedia.org)
  • It is my understanding that starch can be easily hydrolyzed (taken apart with water) at the 1-4 linkage (which starch has) because the amylase enzyme is shaped properly to fit the shape of the 1-4 alpha linkage (lock and key description of the enzyme/substrate specificity). (madsci.org)
  • The amount of amylose in proportion to amylopectin is what basically determines the physical-chemical nature of amylase foods and their nutritional impact on the human organism. (montignac.com)
